Try not to inline tcmalloc::Abort() so we can find it in stack trace.

Suggest simplifying to never call system abort.

It might be useful to pick a specific address (not too far fro m void*(0) to be
modifying, rather than modifying NULL (which is sadly commonly referenced).

char* p = static_cast<char*>(NULL);
p += 57;  // Some interesting and searchable number.
*p = 0;

That might plausible help.... but searching for tcmalloc on crash stack will
probably get you the same results.
